Tl JG-HOOK AND CLEVIS.

SPECIFICATION forming part of Letters Patent No. 235,991, dated December 28 1880.

Application filed August 11,880. (ModeL) 7 To all whom it may concern:

pivot-bar b to the ends of bars d 01.

Be it known that I, LORY BURRELL, of Minneapolis, in the county of Hennepin and State of Minnesota, have invented a new and valuable Improvement in Tug Hooks and Glevises; and 1 do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon. v

Figure 1 of the drawings is a representation of a side view of my improved tug-hook and clevis, and Fig. 2 is a sectional view of the same.

This invention has relation to improvements in hame-tug hooks; and it consists in a tughook and cleviscombined, arranged, and constructed substantially as hereinafter shown and described.

1n the annexed drawings, the letter A designates the hook, constructed with a cylindrical eye, a, arranged in the plane of the same; and B indicates the clevis, composed essentially of two parallel bars at d, an end bar, 7), and two curved bars or connections, 0 c, uniting the The bar 01 has a screw-threaded eye, f, and bar 01 a plain 'eye, g, for the reception of a bolt, 0, having a threaded end, 6, and a head, 0, the said bolt being provided with a sleeve-roller, D, extending between the ends of the bars or arms d d, and. bracing them. The inner faces of the bars 0 c are parallel to each other attheir point of junction to the pivot-bar b, and the ends of the eye a, which encircles the said bar, bear snuglf against the said parallel surfaces 2' i, by which means the hook is prevented from dropping. As indicated in the drawings, the clevis at the bolt 0 is wider than at the pivot-bolt I), thus permitting the use of a Wide tug without using a hook of unnecessarily large size. The roller, also, upon the bolt 0 prevents undue friction and the consequent wear of the tug. The hook, clevis, bolt, and roller are made of malleable iron.

What I claim as new, and desire to secure by Letters Patent, is

The combined clevis and tug-hook, consisting of the clevis B, having the parallel side bars, d d, the curved bars or connections 0 0, provided with the pivot-bar 12, parallel to each other at their point of junction to said pivotbar, the hook A, having the eye a engaging the bar I) and rotating thereon, the removable screw-threaded bolt G, passing through eyesf and g in the ends of bars 61 d, and having the rotating sleeve-roller D, substantially as specified.

In testimony that 1 claim the above I have hereunto subscribed my name in the presence of two witnesses.

LORY W. BURRELL.
